Left atrial pump strain predicts long-term survival after transcatheter aortic valve implantation.

Background: This study aims at investigating left atrial (LA) deformation by left atrial reservoir (LARS) and pump strain (LAPS) and its implications for long-term survival in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI).

Methods: Speckle tracking echocardiography was performed in 198 patients with severe AS undergoing TAVI. Association of strain parameters with cardiovascular mortality was determined.

Safety and efficacy of minimalist transcatheter aortic valve implantation using a new-generation balloon-expandable transcatheter heart valve in bicuspid and tricuspid aortic valves.

Background: Bicuspid aortic valve may be associated with increased complications during transcatheter aortic valve implantation (TAVI).

Aims: Compare balloon-expandable transcatheter heart valve (THV) safety and efficacy in severe tricuspid (TAV) and bicuspid (BAV) aortic stenosis.

Methods: Transfemoral TAVI was performed in 743 patients (Jan 2014-June 2019) using the SAPIEN 3 THV.
